[Font Color Red]

I don't know if this is the right place to ask this, these boards are so confusing. And some of them I must not be authorized to post to because there is not a "new thread" button. So I'm putting my question in here.

I applied a mod I found on this forum to remove the My Favorites link unless the user is logged in. Everything went fine, except now I need to know how to make the "Add to Favorites" link in the Info of the file only show up for logged in users?

I don't want unregistered users, seeing the link "Add to Favorites".
